Physical properties describe characteristics like color, shape, and texture that do not change a substance's identity. Physical changes alter these properties through melting, boiling, or smashing without forming a new substance, while chemical properties and changes involve atomic and molecular transformations that create different materials.

1. Physical PropertiesProperties of the substance that do not change the substance into something newColor, shape, textureBoiling Point, Melting Point, Density, etc

2. Physical ChangeA change to the substance that affects the physical propertiesMelting, Boiling, smashing, etc

3. Chemical Properties Tells how the substance would react.It would change to something new

4. Chemical ChangeChanges the substance into a brand new substance.Rearranges the atomsBonds are broken and new bonds are formedRusting, burning, etc
